What are fetal membranes?

What are fetal membranes?

The fetal membrane surrounds the fetus during pregnancy and is a thin tissue composed of two layers, the chorion and the amnion. While rupture of this membrane normally occurs at term, preterm rupture can result in increased risk of fetal mortality and morbidity, as well as danger of infection in the mother.

Are placenta and chorion the same thing?

Function. The placental membrane separates maternal blood from fetal blood. The fetal part of the placenta is known as the chorion. The maternal component of the placenta is known as the decidua basalis.

How many membranes does the placenta have?

The placenta is composed of three layers. The innermost placental layer surrounding the fetus is called the amnion (Figure 5-30). The allantois is the middle layer of the placenta (derived from the embryonic hindgut); blood vessels originating from the umbilicus traverse this membrane.

Is the placenta from mom or baby?

The placenta does not, technically, belong to the mother. Our bodies may create it, but it is part of the developing child, which means it is also made up of 50 percent genetic material from the father.
